Constantan® is a copper-nickel alloy that contains specific minor amounts of additional elements to achieve precise values for the temperature coefficient of resistivity. Careful control of melting and conversion practices results in a very low level of pinholes at ultra-thin thicknesses. The alloy is used extensively for foil resistors and strain gauges. The TCR can be adjusted from the furnished cold rolled values by using a low temperature heat treatment to achieve compensation for all types of spring elements. The foil is normally supplied with 90% cold reduction and a smooth bright surface. The foil is reasonably flat at 4” wide and nearly free of pinholes. The cold rolled foil can be produced with a TCR between +10 to –35 PPM/°C. The heat treatment will shift the foil TCR to the desired value. A typical heat-treat curve for Constantan® shows decreasing resistivity but increasing TCR with increased heat-treating temperature.

MAGTROL offers a wide range of Load-Force-Weight Transducers with optional integrated electronics or Load Monitoring Units (LMU) with B.I.T.E. functions creating an ideal measurement system which continuously checks for overloads and short circuits. Idealy for use on Safety Applications according to ECE-R10, ISO 13849-1 : CAT4 & PLe and IEC 62061 : SIL3 (LE 6XX SERIES); ISO 13849-1 : CAT2 & PLd and IEC 62061 : SIL2 (LE 4XX SERIES) Magtrol Load Measuring Pins are used to measure load and force, and provide overload protection. The pins are mounted into machines in place of normal shafts and fitted with strain gauges, allowing them to produce a signal proportional to the measured load. Manufactured in Switzerland, Magtrol’s LE Series Load Measuring Pins are rugged with high resistance stainless steel and tight construction. Available in several standard ranges from 2.5 kN to 1 250 kN. .... more information www.magtrol.com

Hot rolled and acid cleaned sheet is enriched by special processes. It reaches the desired thickness by reversible or tandem rolling. At this stage, the sheet is hardened, but becomes formable by continuous annealing or batch annealing. Tempering is applied to improve its mechanical properties. Quality control is ensured through tests and the tempered sheet is shipped in accordance with customer requirements. Cold Rolled Steel Sheet, which is obtained by re-rolling hot rolled and pickled products, has precise dimensions and high surface quality. Product Specifications: DC01, DC03, DC04, DC05, DC06 DC01EK, DC04EK, DC01ED, DC04ED HC260LA, HC320LA, HC380LA, HC420LA Application Areas: Automotive, White Goods, Machinery Manufacturing, Building Industry, Industrial Warehouse Solutions, Panel/Radiator, Fasteners. As Steeling.net, we bring together quality and diversity in cold rolled sheet and offer the highest level of value to our customers.

Cold rolled steel sheets are produced by re-rolling process of hot rolled steel sheets in order to provide precise thickness distribution across the coil. The surface roughness of the cold rolled materials is lower compared to hot rolled steels and suitable for painting and coating applications. According to the customers demands, it can be supplied in coil, slitted and cut to length sheet form. Our stock includes cold rolled steel sheet materials produced according to EN 10130, EN 10268, EN 10338, EN 10209 and others.
